Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is relieved manually. To help prevent serious injury from pressurized ﬂuid, such as splashing in the eyes or on skin, follow the Pressure Relief Procedure when you stop pumping and before you clean, check, or service the equipment.

1. Shut off the air supply to the pump.

2. Open the dispensing valve, if used.

3. Open the ﬂuid drain valve to relieve ﬂuid pressure. Have a container ready to catch the drainage.

Replace Complete Air Valve

4. Align the new air valve gasket (105*) on the center housing, then attach the new air valve. Follow the Torque Instructions, page 19.

5. Reconnect the air line to the motor.
